Sample BDC Model:Connecting to a WCF Service

  • Article

Applies to: SharePoint Server 2010

The following is an example of how to use a set of LobSystem and LobSystemInstance properties to configure connection to a Windows Communication Foundation (WCF) service that uses Metadata Exchange. The MEX endpoint and the service endpoint for a WCF service should be defined in the web.config for your service.

Example
